However, there is a problem in that they cannot be brought close to each other, resulting in a dead space DS on the back.

Further, as shown in the figure, when the continuous paper P is supplied to the printer from the back side of the printer, the continuous paper P is prevented from being caught by the connector 1 or the cord 1c of the connector and causing a paper feeding failure. In order to do so, the paper guide 3 must be projected to the back side of the printer, which causes a problem that the dead space is further increased.

It is an object of the present invention to solve the above problems and to provide a printer capable of remarkably reducing the back dead space.

[0007]

In order to achieve the above object, a printer according to a first aspect of the present invention is provided with a recess in which at least a back surface and a bottom surface are opened, in which a connector is accommodated in a corner of a back bottom surface of a case. It is characterized by that.

A printer according to a second aspect is the printer according to the first aspect, wherein the recess is partially provided in a width direction of the case, and a side portion of the case communicates with the recess. It is characterized in that a concave groove through which the cord of the connector is inserted is formed.

According to a third aspect of the present invention, in the printer according to the second aspect, a hook portion for hooking the cord is formed in the groove.

[0010]

According to the printer of the first aspect, the connector is not protruded from the back surface of the case because the back surface corner of the case is provided with the recess for accommodating the connector.

Therefore, the back surface of the case can be brought close to the wall surface or the like, and the dead space at the back can be significantly reduced.

Moreover, since at least the back surface and the bottom surface of the recess are open, the connecting work and the disconnecting work of the connector can be easily performed.

Further, since the connector does not protrude from the back surface of the case, when the continuous paper is supplied to the printer from the back side of the printer, the continuous paper is not caught by the connector or the cord of the connector, and the paper feeding failure does not occur. There is no longer an increase in dead space as in.

According to a printer of a second aspect, in the printer of the first aspect, the recess is partially provided in the width direction of the case, and a side portion of the case communicates with the recess. Since the concave groove through which the cord of the connector is inserted is formed, the following action is obtained in addition to the action by the printer according to the first aspect.

That is, by inserting the cord of the connector into the groove, the cord can be reliably guided to the side of the case.

Therefore, the protrusion of the cord to the back of the case is surely prevented, and the cord is surely prevented from being caught when the continuous paper is supplied to the printer from the back side of the printer.

According to a third aspect of the present invention, in the printer according to the second aspect, since the hook portion for hooking the cord is formed in the concave groove, the cord is concave even when the printer is lifted. Hard to come off from the groove.

Therefore, there is an advantage that it is possible to save the trouble of inserting the code into the groove again when the printer is moved a little.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of a printer according to the present invention as seen from the lower back, and FIG. 2 is a partially transparent plan view.
FIG. 3 is a partial rear view.

In these figures, 10 is a printer and 1 is
Reference numeral 1 is a printer case. Case 11 is upper case 1
It is composed of 1a and a lower case 11b.

Reference numeral 12 denotes a recess, which is provided at a corner portion of the back bottom surface of the case 11, that is, at a portion where the back surface 11d and the bottom surface 11e intersect, and two interface connectors connected to the printer 10 as shown in FIG. 21, 21 and the power supply connector 22 can be accommodated.

The recess 12 is provided at a substantially central portion in the width direction of the case 11, and the back surface and the bottom surface are open.
